Abstract

A process is specified for desludging waste waters, in which the flushing water containing solid particles is collected in a vessel. The process is suitable in particular for desludging the paint slurry produced during spray-painting in spray cabins and spray booths. The process is that the solid particles produced are kept in suspension by circulation, the solid particles reaching the liquid surface are continuously removed from this and these solid particles are separated off in a centrifuge. The circulation is preferably performed via a pump and spray pipes arranged in the vessel, while for continuous removal of the solid particles from the liquid surface a skimmer is provided, with the aid of which the surface layer of the liquid is removed by suction.
